Windows wont boot after trying to enable ACHI.

[luddomack]

I was trying to enable AHCI on my SSD, by following the steps on the first comment in this post.

 

I only made it to step 6, then the PC crashed or something happend. Now when I start the PC I get to automatic repair, and can't boot Windows anymore. I can't even get Windows to boot in safe mode. 

 

The logfile in automatic repair says "F:\Recovery\WindowsRE\Winre.wim\System32\Logfiles\SrtTrail.txt".

 

I have googled the message and tried every potential "fix" there is for it. But nothing works.

 

Sorry for creating a new post about this instead of commenting the original post, but its looks dead and I need help fast.

 

So, if I could get help that would be fantastic.

 

Thanks!

Try to get a bootible flash-drive of windows.

See if somehow you can edit the registry to restore it. 

You'll have to be creative

You can't just enable AHCI and reboot and expect it to work. You need to set a registry flag BEFORE switching on AHCI in the BIOS, or Windows won't boot. Set your SATA mode back to IDE or whatever it was set as before and retry.

Hmm okey. I actually did not change anything in BIOS.

??? AHCI is a BIOS setting, not a Windows setting.

Well that’s your problem, you can’t just change the windows setting without changing the corresponding BIOS setting...also that guide in OP only works if you have IRST installed.

 

the easiest way way to change the SATA mode after Windows is installed is to set the system to boot to safe mode when you change the SATA mode.

It’s both a Windows setting and BIOS setting

It's not a Windows setting if you configure your BIOS properly, beforehand, though

It is so.  if you want to change it to RAID or IDE you need to change it in both the BIOS and Windows still lol

Okey, I will keep that in mind.

Thanks.
